tion displayed on the Model IAQ10 to
match the concentration on the span gas
cylinder.

a span gas reading. The Model IAQ10
starts a 60-second countdown. When the
countdown reaches zero, the instrument
returns to the normal measurement
mode.
9. With the gas still connected, observe the
reading on the display. It should indi-
cate the span gas concentration. If not,
repeat this procedure.
10. If the displayed reading is accurate,
remove the regulator and tubing. The
calibration is now complete.

instrument off and move DIP switch #7
